REFUSE-BURNER.

SPECIFICATION forming part of LettersfPatent No. 357,108, dated February 1 1887;

Application filed October 14, 1886. Serial No. 216,258. (No model.)

have invented new and useful Improvementsin Garbage-.Oremating Furnaces, of which the following is a specification.

My invention relates to improvements in furnaces for cremating the refuse matter of cities, and has for its object the rapid and complete destruction of such matter in bulk, together with the absorption and consumption of the distilled gases. This objectI accomplish by providing the furnace with improved means for feeding the matter thereto, a reservoir containing a liquid-such aswater-which condenses and absorbs a portion of said gases, and a draft-connection whereby the gases not so absorbed are returned to the furnace below the grate, together with a supply of air necessary for combustion, all of which is more fully pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- I Figure 1 represents a transverse section of a furnace embodying my invention. Fig. 2 is a longitudinal section thereof in the plane a: :0, Fig. 1. Fig. 3 is a horizontal section in the plane 3 3 Fig. 2. Fig. 4 is an end elevation. Fig. 5 is a longitudinal section, on a larger scale than the precedingfigures, of the blast-nozzle.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a shell which is made of boiler-iron or other suitable material and incloses the furnace. WVithin the shell are located two bridge-walls, B B, which extend longitudinally through the and form with said shell lateral spaces that are in communication atthe top with the firebox 0. 'These spaces are filled with some liquid-such as water to a determined level,- and I shall hereinafter term the same the condensers D D. The bridge-walls arelined on the condenser side with sheet metal.

The grate E extends through the length of the furnace, and may be of any suitable construction to discharge into the ash-pit F, Fig.

1. Furnace-doors at each end of the grate facilitate the firing.

The refuse matter, animal and vegetable,

intended for cremation in this furnace is not previously assorted. as has heretofore been the usual practice, and for this reason care must be taken in feeding such matter, so as not to overcharge the furnace. To afford means for putting the charging of the furnace under the control of the attendant, I provide the furnace with a hopper, G, which is secured to the crown of the shell A and has its upper or receiving portion constructed with inclinedwalls, while its lower or discharging portion has outwardly-flaring walls to effect a proper distribution of the garbage. Within the receiving portion of the hopper G are located pivoted and balanced feeding-plates H H, Fig. 1, which diverge as the garbage is thrown thereon and allow the same to pass through but close against a partition, I, immediately after the discharge of such garbage has taken place. The feeding-plates can be balanced by means of springs; but I prefer to balance them by means of weighted arms 71- h, that are secured to the shafts of said plates, the said shafts projecting through the shell A. The weights being adjustable on the arms, the feedingplates H H can be set for different weights of garbage. As the hopper G is divided by the partition I, one or both compartments of the same may be used at a time.

The partition I is continued below the hopper G, and is provided at its lower end with hangers t i, which support the shafts j j of two quently well dried, being'also exposed to the the before it is dumped on the fire-grate.

In the cremation of animal and vegetable garbage gases arise, part of which are soluble in water, and these Ipropose to condense and collect in the condensersD D before mentioned. To compel the products of combustion to pass through these condensers,a deflecting-plate, L,

is located at the rear of the condensers, the end of which dips into the water and forms a seal. This deflecting-plate closes the combustion-chamber at the rear of the furnaces and the insoluble gases are conducted to a smokebox, M. Vater is supplied in a continuous spray by perforated pipes or water-distributers N, which are located in the condensers, at or near the top of the same, so that the gases must come into contact with the spray, and are condensed thereby. Cold water is supplied to the distributers by a pump or other forcing device. Overflow-pipes N, Fig. 2, determine the level of the water in the condens ers and conduct the saturated water to any suitable point. r I

The combustible or insoluble gases which have not been consumed are drawn from the smoke-box by a blower, O, and are forced into the furnace below the fire-grate,together with a supply of fresh air. The pipe 0' from the blower is branched for two or more points of supply, and each branch has a contracted end or nozzle, 0, which is surrounded by a perforated cone,P, which projects into the fire-box, so that a constant supply oi'air is drawn through said cone P with the gases from the smokebox, and a rapid and complete combustion of the gases is insured, while at the same time the temperature of the furnace becomes so intense as to consume all the matter on the grate.

By the use of my improved fu nace all the gases arising from the cremation ofthe garbage are either taken up in solution or consumed, and consequently none of the obnoxious and injurious gases can impregnate and pollute the surrounding atmosphere.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. The combination,-in a furnaee,of the shell A, the upright bridge-walls B B, separated from each other to form the fire-chamber and from the outside of the shell to form the condensing-chambers D, which communicate with the fire-chamber above the bridge-wall, afiregrate between the bridge-walls, and a feeder for feeding the material between the bridgewalls, substantially as described.

2. The combination, in a furnace, of the shell-A, the upright bridge-walls B, forming the fire-chamber, the condensing-chambers D at the sides of the bridge-walls, and the perforated water-distributing tubes N in the condensing-chambers, substantially as described.

3. The combination, in a furnace, of the shell A, the bridge-walls B, forming the firechamber, the condensing-chambers D at the sides of the bridge-wall, and the deflectingplate L, for directing the products of combustion to the condensing-chambers, substantially as described.

4. The combination,in a furnace, of a shell, A, the bridge-walls B, incloscd by the shell and forming a fire-chamber, a fire-grate, E, between the bridge-walls, the condensingchambers D at the sides of the bridge-walls and in communication with the fire-chamber, a blower, 0, having a suction-pipe connecting with the condensers, and a discharge-pipe communicating with the furnace beneath the firegrate, substantially as described.

5. The combination, in a furnace, of a shell, A,the bridgewalls B therein, forming a firebhamber, the condensers D at the sides of the bridgewalls, a grate, E, in the fire-chamber, a smoke-box, M, at the rear of the furnace, a blower, 0, having its s'uctionpipe connected with the smoke-box and provided with a dischargepipe having a nozzle, and an air-cone entering the shell beneath the fire-grate and receiving the said nozzle of the blower discharge-pipe, substantially as described.

6. The combination, with a furnace having a combustioirchamber, of a feed-hopper, G,

located above the combustion-chamber, a par tition, 1, extending vertically through the hopper, and the weighted feeding-plates H, pivoted respectively at the sides of the hopper and closing at their lower edges against the partition, substantially as described.

7. The combination, with a furnace having a combustion-chamber, a fire-grate, E, in'the lower portion thereof, and the bridgewalls B B, of afeed'hopper, G, located above the combustion-chamber, the two depending grates J, both pivoted at their upper ends adjacent to each other beneath the hopper and closing at their lower edges against the bridge-walls and opening toward the center of the combustionchamber, and means for opening and closing said grates, substantially as described.

8. The combination of the furnace-shell A, the bridgewalls B, forming a combustion: chamber, a feed-hopper, G, located above the combustion chambcr, a partition, I, extending through the hopper and having hangers t atits lower end, the shaftsj, hung in said hangers and carrying the depending dumpinggrates J, which close at their lower edges directly against the bridge-walls and open to ward the center of the combustion-chamber, means for opening and closing the grates, and feeding-plates in the hopper closing at their edges against the partition therein, substantially as described.
